libsel4: consistent definition of seL4_PGDBits

Browse source 
Previously seL4_PGDBits was calculated, which is inconstent with the rest
of the composite constants in libsel4, and makes size constants harder
to parse from the C.

This commit makes seL4_PGDBits consistant with other definitions, by making the definition an integer and checking it with a compile time assert.
